The observations analyzed here were made on 26 September and 6 October 1996 as part of a comprehensive investigation of the infrared spectrum of comet Hale-Bopp with ISO (Crovisier et al. 1997a, 1997b). The full spectral scan (43-195 µm, spectral resolution , field of view ) obtained on 6 October with the Long Wavelength Spectrometer (LWS; Clegg et al. 1996) was re-reduced using the last version (7.0) of the standard pipeline (Fig. 1). The photometer grating spectrometer (PHT-S; Lemke et al. 1996) observed the 2.5-5 µm spectrum (spectral resolution , field of view ) on 26 September and 6 October.
